Abstract

A sleeping device for stabilizing the legs of an individual during sleep to maintain the individual's back in a desired position. The inventive device includes a first engaging member pivotally coupled to a second engaging member. The engaging members cooperate to receive adjacent portions of the individual's legs to maintain the legs in a spaced and parallel orientation.

Claims

exact text as granted — not AI-modified
What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows: 
     
       1. A leg stabilization sleeping device comprising: a first engaging means adapted to receive a portion of a first leg of an individual;   a second engaging means adapted to receive a portion of a second leg of an individual;   each of the engaging means being substantially similar in shape and configuration and comprising a U-shaped interior frame including a substantially semi-cylindrical center section having opposed lateral ends with a pair of lateral sections projecting from the lateral ends and into a substantially spaced and parallel orientation relative to one another to define a substantially U-shape of the engaging means, each of the engaging means further comprising a resilient foam material coupled along an interior surface of the U-shaped interior frame and extending coextensively therewith; and an exterior skin encapsulating both the interior frame and the resilient foam material to enclose together the interior frame and the resilient foam material, the U-shaped interior frame comprising a substantially resilient plastic material, the plastic material being resiliently deformable to permit resilient and frictional engagement of the leg of an individual positioned between the lateral sections and into contact with the semi-cylindrical center section; and,   a coupling means adapted to pivotally couple the first engaging means relative to the second engaging means, the coupling means comprising a first mounting block coupled to an exterior surface of the semi-cylindrical center section of the first engaging means; a pair of pivot plates coupled to the first mounting block and positioned in a substantially spaced and parallel orientation relative to one another; a second mounting block coupled to an exterior surface of the semi-cylindrical center section of the second engaging means; a cylindrical pivot tube mounted to the second mounting block and positioned between the pivot plates; and a pivot pin extending through both of the pivot plates and the pivot tube to pivotally couple the first mounting block relative the second mounting block, whereby the first one of in individual's legs can be received within the first engaging means, the second one of an individual's legs can be received within the second engaging means so as to position and maintain the legs in a spaced and parallel orientation during sleep.
